    Problem: Page incompletely rendered

    Travers Naran Newbie

      I'm having a weird problem with my application.

       

      Sometimes, when rendering the page, it will only render some of the elements.  I hit refresh, it renders the entire page normally.  When I use FireBug, it looks like it's a complete response from the server but chunks of the page weren't rendered.

       

      The chunks don't have "rendered" attributes or anything else that should interfere with rendering.  I see nothing in the log file indicating an error or exception.

       

      This especially happens when doing post-back page submission/navigation, not the partial re-renders of RichFaces/A4J.

       

      Let me know what further information I can provide.

       

      Thanks in advance!

            The pages in question run almost a 100k.  I can't seem to re-create this with smaller pages, but I can show you the high-level page markup.

             

            First off, I'm using Facelets and ui:composition for templating.  The top template is:

             

            layout.xhtml:

            {code:xml}
            <?xml version="1.0" encoding="ISO-8859-1" ?>

              Couldn't seem to edit that post properly.
